I'm with Raoul, on both film and camera recommendations. The C-41 B&W films would be nice if you need more speed, but do some testing to find out their EI for you; I think they are better exposed at 250 or so EI.
I really like Delta 400 also, developed in Xtol at 1+2 or 1+3. Of course, you'll have finer grain at a higher developer concentration, but I really like the tones with a more dilute developer.
Good luck with your project.
